Upgrade to Ubuntu 16.04 and bringing Magento 2 back to life

I upgraded from Ubuntu 14.04 to Ubuntu 16.04 lately. This brings the joy of PHP 7.0.4 and Apache 2.4. As I run Magento 2 locally for testing purposes, I found it did not work anymore after the upgrade.

Actually I had 3 problems:

1.) Missing PHP extensions

I decided to start a new Magento 2.0.5 setup to check the requirements. From there I found out that I was missing some PHP extensions, so I installed them:

sudo apt-get install php-curl
sudo apt-get install php-intl
sudo apt-get install php-mbstring
sudo apt-get install php-zip

2.) MySQL

After reloading the Magento 2 front page, I got a strange SQL error on the fronted (sorry, I did not copy the error message). I found out that also MySQL workbench did not like to connect to my local MySQL server („[ERROR] Native table ‚performance_schema‘.’session_variables‘ has the wrong structure“ and some more). Somehow it seemed that also MySQL was not running, so I started and restarted MySQL and everything was fine again. Hm.

3.) Enable Apache 2.4 rewrites

The homepage came back on screen, but I was not able to open the admin login page or any other pages. I thought this would have been caused by a missing mod_rewrite, but this was in place.

Somehow I ended up on the devdocs where a solution for the Apache 2.4 rewrites was in place:

Just add the following piece to your 000-default.conf file:

sudo nano /etc/apache2/sites-available/000-default.conf
<Directory "/var/www/>
 AllowOverride All

Hope this helps anyone running into the same problems.

Oh, and btw: Make sure you run at least Magento 2.0.1 for PHP7 fun 🙂
